Care/of is not taking new customers anymore. Bayer, which bought the personalized vitamin brand in 2020, wound down its consumer subscription business in 2024, and the app and quiz have been offline since. We are reviewing it anyway because search traffic for "Care/of review" has not slowed down, and the honest answer readers deserve is what the packs actually contained when we tested them, not a pretend current buying guide for a service that no longer exists.
The short version: Care/of's quiz was better at marketing than at nutrition science, the packs we received were correctly dosed against the labels but not meaningfully more personalized than a well-chosen multivitamin, and if you are shopping today, Ritual and Persona are the two active brands doing the closest version of what Care/of promised.
This review documents what we actually tested, then points you at what replaced it.
What Care/of Actually Was, and Why We Are Still Reviewing a Discontinued Service
Care/of launched in 2016 as a direct-to-consumer quiz brand: answer questions about diet, sleep, stress and goals, and an algorithm assembled a daily pack of individually wrapped vitamins and supplements shipped monthly. Bayer acquired a majority stake in 2020, folded it into its consumer health division, and by mid-2024 had stopped taking new signups and shut the backend down entirely. Existing customers received a wind-down notice and a final shipment window.
We keep this review live, updated to say plainly that the service is gone, because a reader who typed "Care/of review" in 2026 is almost always deciding between whatever is still active, not trying to place a new Care/of order. Treating the page as though the company still operates would be the kind of stale, misleading content this site exists to avoid.
How We Tested These Vitamin Packs
We signed up for Care/of during our original supplement testing window, before the wind-down was announced, completed the intake quiz twice under two different health profiles, and took the resulting daily packs for six weeks. We logged every capsule and gummy against its label, checked the amounts against the tolerable upper intake levels the National Institutes of Health publishes for each nutrient, and priced the true monthly cost including the one-time starter kit fee. We did not track any biological outcome, because six weeks of pill-taking produces no measurable change worth reporting, and a subscription quiz is not designed to.
What Was Actually in the Packs We Received
Both of our profiles landed on a base multivitamin plus two or three add-ons: a vitamin D softgel, an omega-3 fish oil capsule, and in one profile a magnesium glycinate tablet flagged for "sleep support" language that we found softer than the ingredient itself justifies, since magnesium's evidence for sleep is limited and mixed rather than settled. The doses on every product we received matched what the label stated, and none exceeded the upper intake level for an adult. What we could not verify was a batch-specific certificate of analysis; Care/of's marketing referenced quality testing in general terms without naming a specific third-party certifier such as NSF or USP for every product in the mix, which is a lower bar than brands like Thorne or Nordic Naturals hold themselves to.
The quiz itself asked reasonable intake questions, but the personalization ceiling was low: two people with meaningfully different diets and the same stated goal of "more energy" received overlapping base formulas with only the extras swapped. That is closer to a smart multivitamin picker than the individualized nutrition plan the marketing implied.
Care/of Against the Personalized Vitamin Brands Still Taking Orders
| Brand | Status in 2026 | Personalization method | Third-party testing disclosed |
|---|---|---|---|
| Care/of | Discontinued, no new orders | Quiz-based pack assembly | General claims, not certifier-named per product |
| Ritual | Active | Fixed formulas by life stage, not a quiz | NSF Certified for Sport on select lines, batch tested |
| Persona Nutrition | Active | Quiz plus dietitian consult option | NSF and cGMP facility testing named per product |
If a quiz-driven pack is genuinely what you want, our Persona Nutrition review covers the closest surviving version of the Care/of model, consult option included. If you would rather skip the quiz and pick a fixed, well-documented formula for your age and sex, Ritual is the simpler and better-tested option we would point a reader toward today. Either way, start at our best supplements guide before committing to a monthly subscription, since the right choice depends heavily on what you are already eating.
What Six Weeks of a Quiz-Based Pack Taught Us About the Category
The broader lesson from testing Care/of, and one that still applies to every quiz-based supplement brand on the market today, is that an intake form built for marketing conversion and an intake form built for nutritional accuracy are not automatically the same thing. Care/of's questions covered diet pattern, stated goals and a handful of lifestyle factors, similar in structure to what Persona and several smaller competitors still ask. None of these quizzes can see a blood panel, a current medication list or a family history, which is exactly the information that would actually change what supplementation, if any, makes sense for a given person.
That gap is not a flaw unique to Care/of. It is a structural limit of any subscription intake form, and it is the reason we keep coming back to the same closing point across every supplement review on this site: a quiz can narrow down options and flag obvious gaps, like a diet with no dairy and no fortified foods pointing toward a vitamin D and calcium conversation, but it cannot replace bloodwork or a clinician's judgment. Readers shopping any of Care/of's surviving competitors should treat the quiz result as a starting point for a conversation, not a finished prescription.
Where Personalization Ends and a Doctor's Advice Begins
Nothing in this review is a recommendation to start, stop or change a supplement regimen, and a quiz, however well built, cannot see your bloodwork, your medication list or your family history. Anyone on blood thinners should talk to a doctor before adding a multivitamin that includes vitamin K, since it can blunt the drug's effect. Anyone pregnant, nursing, managing a chronic condition or taking prescription medication should clear any new supplement stack with a clinician first, not a subscription quiz. We are reviewers who checked labels and doses against public reference values; we are not the person who can see your full medical history, and no personalization algorithm is either.
The bottom line: Care/of no longer exists as a service, and the packs we tested before it shut down were accurately dosed but only lightly personalized, so readers looking for an active quiz-based option should look at Persona, and readers who want a simpler, better-documented formula should look at Ritual.
